IrfanView PSD Image Parsing Multiple Vulnerabilities

Multiple vulnerabilities have been identified in IrfanView, which could be exploited by attackers to compromise a vulnerable system.

1. A sign-extension error when parsing certain PSD images can be exploited to cause a heap-based buffer overflow by tricking a user into opening a specially crafted PSD file.

2. A boundary error when processing certain RLE compressed PSD images can be exploited to cause a heap-based buffer overflow by tricking a user into opening a specially crafted PSD file.

Successful exploitation of the vulnerabilities may allow execution of arbitrary code.
